Ezekiel 38:16-17

and you will attack my people Israel, covering their land like a cloud. At that time in the distant future, I will bring you against my land as everyone watches, and my holiness will be displayed by what happens to you, Gog. Then all the nations will know that I am the LORD. “This is what the Sovereign LORD asks: Are you the one I was talking about long ago, when I announced through Israel’s prophets that in the future I would bring you against my people?
